RESUMO:
Contamination of soil by dangerous organic pollutants has been gaining attention in recent years. Within this scenario, this work studies and evaluates the efficiency of the application of electrokinetic remediation (EKR) in soils contaminated by petroleum. In association with the conventional method of EKR, we introduced oxidant electrolytes (Hydrogen peroxide and Fenton reagent) and also analyzed the SDS surfactant application to evaluate the solubilization of the organic component in the aqueous medium and in situ degradation in order to achieve some improvement in the treatment of this contaminant. The generated effluents (electrolytes contaminated with petroleum) were also treated by Fenton and Solar Electro Fenton (SEF) process. The results obtained were promising. Soil decontamination was more efficient when we used the fenton reagent (99% near the anode, followed by 97% in the intermediate zone and 94% near the cathode). For Exp-1 we had rates of 78%, 88% and 93%. For exp-2, 92%, 88% and 90%. Effluents also achieved excellent degradation rates for Exp-1, with 96.7% and 95.7%, for exp-2 with 88.7% and 93.3% of SEF and EF, respectively. At exp-3, we obtained 62.22% in SEF. Fe2+. Interferences in Exp-3 should be considered.
